Does anyone know what the regs are concerning aux. tanks? The only thing I'm wondering is how much fuel can I carry without requiring a hazardous materials permit? I know it must be a lot more than i plan on, but its worth asking. I'm going to be installing 2 or 3 additional tanks in the back of my truck. No, I don't drive long distances, but I do want to be able to take advantage when I find low priced fuel somewhere. The tanks I have are around 25 gallons each, so that would be 75 gallons in addition to the stock 35 gallon tank. I will probably make them removable so I don't need to carry them all the time.

If I'm not mistaken you can haul around as much fuel as you want as long as it isn't commercial.
To be absolutely sure contact one of the aux tank manufacturers.

We are allowed 3 drums of oil on our work truck without a hazmat plaquard and hazmat rated driver. Not sure about private. Probably what ever you can get away with.

Just remember diesel weighs ~7 lbs per gallon.
The extra weight will reduce your MPGs.

I have a 51 gal aux tank and between full and empty I have zero difference in mpgs. An extra 300 or so pounds doesn't mean much to the Cummins. I'm sure by some miniscule amount it could theoretically lower your mpg, but it's not enough to worry about.

I know a few guys with 110 gal aux tanks that are non commercial, and they have no issues. Granted, a permanently/safely mounted tank would probably not be looked twice at, compared to someone hauling around drums of something that could theoretically fall out and cause a major mess/problem..

You'll have to look this up at the DOT website to be absolutely sure, but transfer type tanks, (like the kind you'd use to fill equipment on a job-site), I think, are limited to 110 gallons before you need to placard the vehicle that is carrying it. You *might* find the needed info at; http://www.fmcsa.dot.gov/ IF you have the time to wade thru the site for the next few hours!

Have fun!

Thanks guys. I have been thinking about it, and although the idea of buying up as much fuel as possible when its cheap sounds great, I think I'll limit my aux. tanks to two 25-gallon tanks. Even if I find "cheap" fuel at $2.50/gal., it would cost over $200 just to fill the truck's tank and the 2 aux. tanks. I think thats plenty of hit to the wallet at once, for someone who isn't using the truck commercially. I just want the capacity, since fuel varies so much.

Here in Washington state you can carry up to 119 gallons in a single container w/out being regulated. At 120 you have to jump through many hoops. Here is the catch; you can run around with 10 119 gallon tanks if you want w/ out regs. Also you can not legally fill your primary tank from an aux tank by hanging the hose over the bed rail. You can however plumb into your existing tank for a perm application.

Ahh, it's 119 now. I knew they changed it a while back. It used to be 99 gallons and I know they increased the non-placarded amount, but couldn't remember to WHAT!
